Compact, UAV compatible 2D Spectrometer for multi-species atmospheric gas analysis

Gouman, J.; Renevey, P.; Dasen, S.; Chin, S.; Herr, T.; Buchs, G.; Lütolf, F.; Lecomte, S.; Vergara, G.; Martin, H.; Moselund, P. M.; Harren, F. J. M.; Balet, L. (2019)

We present an UAV compatible spectrometer designed for sampling air pollutants in remote locations. Relying on a custom-made Multi-Pass Cell and a 3-5 µm broadband supercontinuum light source, it takes advantage of an ...
Confined electron and hole states in semiconducting carbon nanotube sub-10 nm artificial quantum dots

Buchs, G.; Bercioux, D.; Mayrhofer, L.; Groning, O. (2018)

We show that quantum confinement in the valence and conduction bands of semiconducting single-walled carbon nanotubes can be engineered by means of artificial defects. This ability holds potential for designing future ...
Nuclear spin decoherence time in MEMS atomic vapor cells for applications in quantum technologies

Buchs, G.; Karlen, S.; Overstolz, T.; Torcheboeuf, N.; Onillon, E.; Haesler, J.; et al. (2018)

We report on the fabrication and characterization of MEMS atomic vapor cells suitable for applications in miniaturized quantum sensors such as atomic gyroscopes. Our MEMS cells are filled with natural abundance Rb alkali ...
